We found that 55% of the workers had a measurable concentration of inhalable Cr(VI), with 19% exceeding 1 µg/m3, a level that corresponds to an \"upper risk level\" for future EU binding occupational exposure limits over a working lifetime. Additionally, 52% of workers had red blood cell (RBC) Cr concentrations exceeding the 95th percentile of an unexposed control group. Among responding workers (n = 91), 35% reported to perceive to be at no or low risk due to Cr(VI) exposure, 47% to be at some or large risk while 18% stated to be unsure. No correlations were found between reported risk perceptions and measured inhalable Cr(VI), urinary Cr, or RBC-Cr, but a weak correlation to years employed was found. Observations indicated that the hierarchy of controls was not strictly followed. Furthermore, 42% of respiratory protective equipment users used it incorrectly, and only two out the 50 (4%) needing a fit-test reported having performed one. Interviews with the managers revealed a lack of knowledge about the health risks of Cr(VI), and that expectations about exposure levels did not always match measured exposures. Our findings identify knowledge gaps regarding the health hazards of Cr(VI) and highlight the difficulty of estimating workplace exposure and risk without measurements. Based on our findings we recommend efforts to improve knowledge about Cr(VI) health hazards, strengthen the adherence to the hierarchy of controls, and incentivize quantitative exposure assessments.</p>","PeriodicalId":8362,"journal":{"name":"Annals Of Work Exposures and Health","volume":" ","pages":""},"PeriodicalIF":1.8,"publicationDate":"2025-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144558848","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We know that the physical behaviours the workers do at work are important for their musculoskeletal health and sick leave. However, we lack knowledge of which workplace factors determine the physical behaviours of workers. Therefore, we aimed to investigate which organisational levels and factors of Danish day nurseries determine the physical behaviours at work of childcare workers.</p><p><strong>Methods: </strong>This cross-sectional study included 178 childcare workers from 73 teams and 16 day nurseries in Denmark. Workers were, on average, 36.5 years of age, mostly female (84%) and 57% were educated pedagogues. We measured physical behaviours (i.e. sedentary, light physical activity, and moderate-to-vigorous physical activity) during working hours using a thigh-worn accelerometer, and expressed them as isometric log-ratio coordinates for analysis according to compositional data analysis procedures. We examined 15 potential determinants of physical behaviours at work at three organisational levels: institutions (e.g. permanent-to-not-permanent staff ratio), teams (e.g. worker-to-child ratio), and workers (e.g. age, BMI, physical exertion). Variance component analysis identified the percentage contribution to the total variance of physical behaviours of each organisational level.
